pomp version 2.8 has been released to CRAN and is on its way to a mirror near you.
Important Changes
-
As promised with version 2.4.1.3, the default value of
tol
in the particle-filtering algorithmspfilter
,pmcmc
,mif2
, andbsmc2
has been changed to zero. A warning continues to be issued iftol
is set to anything other than 0. In a future release, the option to choose a nonzero tolerance will be removed entirely. This change is not backward compatible. If precise reproduction of old results is needed, set thetol
parameter to the appropriate nonzero value. -
In traces and diagnostic plotting methods, the
nfail
variable (tracking numbers of filtering failures) has been dropped.
Minor change
- The Euler step size in
sir
is now adjustable by means of the argumentdelta
